CW'OVEQN FABRIC.

SPECIFICATION forming part of Letters Patent N0. 653,595, dated July 10, 1900. Application filed Iannary 2?,1900. Serial No. 2,325. (No model.)

To all whom it may concern/.-

Be it known that I,WILLIA M. STEVENSON, a citizen of the United States, and a resident of Indian Orchard, Hampden county, Massachusetts, have invented certain Improvements in Woven Fabrics, of which the following is a specification.

The object ofmy invention is to form a two-i objectionable appearance known "as grin nin My invention also provides for the binding of the weft or filling threads on'the face of the fabric always with warp-threads of their.

own color. 7

In carrying out my invention I shed the binding warp-threads in pairs, the two threads lying side by side wherever they bind a weftthread on either face of the fabric, but the pair being split between the plies Wherever it is desired to. bind the two plies together, so that one thread of the pair may engage with a weft of the back ply and bind it firmly against the face ply, the remain g warp-thread of the pair, however, preventing such weftthread of the back ply from being drawn up between the weft-threads of the face plyat the binding-point.

In the accompanying drawings, Figure 1 is an exaggerated section taken in 'the line of the warp and illustrating a fabric woven in accordance with my invention, but showing the two plies separated from each other in order to illustrate more clearly the course of the Warp-threads; and Fig. 2 is a View illustrating the disposition of the various warp.

and weft threads of the fabric, the weft threads of the back ply, however,beingshowri' -In the fabric shown in thedrawings there are repetitions of successively-inserted weftthreads 1 and 2 interwoven with pairs of warpthreads to form face and back plies. Thus the weft-threads 1 are interwoven with warpthreads 1 1' and 1 1 to form one ply and the weft-threads 2 are interwoven with the warpthrea'ds 2 2 and 2 2 to form the other ply,

the plies changing from face to face in accordance with the demands of the pattern. Each pair of warp-threads is shedded as a unit in theordinary weaving of the fabric, so that the two threads of the pair appear side by side over a weft-thread where they bind the same on the face or under the weft-thread where they bind it on the back; but the pairs of warp-threads of the face ply are split at intervals 'between' the plies, "so that one warpthread of the pair may engage with a weft thread of the back ply and bind the same up to the face ply while the other warp-thread ,of the pair prevents the pulling through of said weft-thread of the back ply between the wefts of the face ply. The tying duty is preferably performed first by awarp-thread of one pair of the face ply, then by a warp thread of the next pair in said ply, then by invention has the plies firmly bound together at all points, and hence is without bags or pockets, while the grinning of weft-threads of the back ply between weft-threads of the face ply is effectually prevented.

i. Having thus described my invention, I claim and desire to secure by'Letters Patent'-.

1. A woven fabric in which sets of weftthreads are interwoven with sets of warpthreads to form adouble ply,the warp-threads being shedded in pairs to bind the weft threads, but the pairs on the face ply being split at intervals between the plies, and one warp-thread of a pair in the face ply being caused to engage with a weft-thread of the back ply and tie the two plies together, while the other warp-thread of the pair in the face ply prevents said weft-thread of the back ply from being drawn up between wefts of the face ply, substantially as specified.

2. A woven fabric in which sets of weftthreads are interwoven with sets of warpthreads to form a double ply,the warp-threads being shedded in pairs to bind the weftthreads, but the pairs on the face ply being split at intervals between the plies, and one warp-thread of a pair in the face ply being caused to engage with a weft-thread of the back ply and tie the two plies together, while the other warp-thread of the pair in the face ply prevents said weft-thread of the back ply WILLIAM M.
